The Answer Depends on the Next Search
TL;DR for operators An internal research assistant may need to discover several technical relationships before it can answer a question. Selecting documents or graph records only once, before reasoning begins, can exclude relationships that become relevant later. Prospector1 demonstrates that this search behavior can be learned by a compact 4B-parameter language model. On 195 semiconductor questions, it achieves 83.9% single-pass accuracy, compared with 87.7% for the strongest evaluated frontier model using the same graph tools. Selecting among 32 sampled episodes with a trained verifier raises Prospector’s score to 91.3%, but adds substantial inference work. ...
